GRAPHENE PRODUCTS
Graphene coated Heat Sink
Product:
Coating the nano-carbon thermal ink onto the surface of aluminum foil and copper foil as the advance heat sink products.
Features:
1. TRA and TRC Series are the thinner heat dissipation materials, lowering the heat dissipation efficiently, and feasible to eliminate the heat spot.
2. TRA and RC Series with the thickness between 0.05 mm to 0.4 mm, it is the best design choices on dimension consideration. It can be made to any shape, convenient to use in different products, especially the electronic products with a confined space.
3. They are flexible, light-weight, and cost effective. Due to its compact design, it does almost not add the additional weight for products. ThermoRay is also easily handling for manufacturing process.
4. TRA and RC are new heat dissipation material with the nanomaterials of high emissivity. It can replace the traditional heat pipe and the aluminum heat-sink for working efficiently in compact design.
5. Compared to the graphite sheet material with only high X-Y-axis heat conduction, TRA and TRC has pretty good effect of heat transfer at 3D direction.
6. High surface area structure can enlarges the heat dissipation efficiency. Not only the heat convection but also thermal radiation.
